Guhring 9055120053000 Taper Length Drill Bit 0.2087 in

Product Description

The GUHRING 9055120053000 is a solid carbide taper length drill bit designed for precision hole-making in demanding materials. Built to DIN 6537 standards, it features a 140-degree split-point (SU) geometry with web thinning for self-centering entry and reduced thrust. The 5.30 mm (0.2087 inches) diameter bit has a 7xD flute-to-diameter ratio, a 1.9685-inch spiral flute length, and a 3.8189-inch overall length. Internal coolant-through capability supports high-speed drilling in production environments. The straight shank measures 0.2362 inches in diameter. This bit is installed by machinists and tool-and-die professionals working in metalworking and manufacturing operations.

The 9055120053000 is engineered for drilling brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy. Its submicron carbide grade and coated finish extend tool life in abrasive and work-hardening materials. With a maximum drilling depth of 1.6560 inches (42.05 mm) and a tapered web configuration, it suits CNC machining centers and manual drill presses where consistent bore quality is required across high-volume runs or precision one-off parts.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in hard and abrasive materials
• 140-degree SU split-point geometry with web thinning for self-centering, reduced-thrust entry
• Coolant-through design supports high-speed and deep-hole drilling operations
• Coated finish extends tool life when drilling stainless steel, nickel alloy, and titanium alloy
• 7xD flute-to-diameter ratio provides chip clearance in deeper cuts
• Conforms to DIN 6537 standard for consistent dimensional accuracy

Compatibility

Designed for use in CNC machining centers and drill presses accepting a straight shank diameter of 0.2362 inches. Suitable for drilling brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy per Series 5512 application specifications.

Installation Notes

This drill bit is installed by machinists in milling machines, CNC machining centers, or drill presses using a collet or drill chuck sized for a 0.2362-inch straight shank. Ensure the spindle and workpiece are secure before beginning a cut. When using the coolant-through feature, verify coolant supply lines are connected and pressurized to the machine's specified operating range before running the spindle. Inspect the cutting edge for wear or chipping before each use, as carbide tooling is brittle and susceptible to damage from interrupted cuts or improper handling.
